ABSTRACT:
A toothbrush for use on domestic pets, comprising a toothbrush head with each end curved upward at roughly 30 degree angles, and four sets of soft bristles attached to the head. Three sets of bristles are attached to the front face of the brush head, with two sets positioned opposite each other on each upward curved end of the head and the third set of bristles positioned in the center in the middle region, perpendicular to the toothbrush head between the other two sets, thereby providing coverage of the mesial, distal and occlusal surfaces of the teeth simultaneously. The fourth set of bristles is attached to the back side of the toothbrush head, thereby propping open the jaw and softening the bite while cleaning and massaging the opposing teeth at the same time that the other three sets of bristles are doing the primary cleaning. The toothbrush handle is attached to the center of the head for ease of use and the ability to reach the back molars.
